sql - Communication between two computers and a database -


i'm student programmer , i've landed task @ job develop software system monitor when employee's clock in, clock out, , log times. employee's use keypad attached computer @ front desk enter employee id gui clock them in/out. there's gui office manager use monitor employee in , outs, , keep track of who's in office.

the project windows form project in vs 2010, 2 gui's (as mentioned), , access 2007 database store data. office manager gui has datagridview object i'd populate employee name, , time (s)he clocks in or out. happen in real time. in other words, once employee clocks in, populates in office managers gui. i'm looking best practice approach. should take client/server approach? should have trigger database alert office manager gui fire event clock in/out time of employee populated office managers datagridview?

the database , queries have been designed. i'm looking best practice approach problem. i'm junior level college student , come stackoverflow.com time. first question, either way big step me :) in advance.

if microsoft aligned (and using .net etc) may find easy enough take sql express route (all tools microsoft design similar , integrate quite together).

you can download sql express advanced services (any version 2005 onwards should fine project, long includes management studio, , might want reporting services)

my approach poll database every , monitor changes in clock in/out table(s).

i not use access it's not best solution actual database , doesn't scale particularly well. whilst work fine project, it's worth getting hands on sql server experience it.

i'm assuming clocking in/out view show page of employee names, , based on date - in case firing query every 5-10 seconds @ database current state won't cause issues.

whilst it's possible push notifications sql client, easy if not easier rig timer @ client end , won't cause performance impact in application of scale

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
